If you're NOT working, I suggest the Netherland Hilton at 35 West Fifth Street, downtown. It's an art deco gem and has one of the finest in-house restaurants anywhere. Most of the free-standing restaurants are closed due to the COVID-19 issue.
If you are working, I suggest staying in Covington, Kentucky, just across the river. The Courtyard by Marriott has in-room jacuzzis in some rooms that are comfortable for 2-3. Stay away from the
Springdale area.
Have a wonderful time---it's a great city. If so inclined, the Zoo is one of the 2-3 best in the nation.
